Today is a good day. I'm very happy I got my pair replaced by the ebay seller... (keny-lin). I had to ship my defective pair back to China (cost like 20$), i had to wait 4 weeks...but it was definitely worth. I got a new pair of GR07BE and I simply LOVE their sound. I can say it is addictive and I missed it all this time.
Meanwhile I bought also a JVC FXZ100 as I needed some portables, they have powerful and great bass, but otherwise I think the GR07 are much better. The details are impressive and at this moment I cannot wish more from a pair of headphones. I'm not an audiophile, but I can appreciate a balanced and fairly neutral sound. The Gr07BE are amazing IEMs. So happy I got them back! :)
Why don´t you consider the gr07 portables? Don´t they fit you good enough to use them outside?
